Title : The Beer-Lambert Law and Its Limitation Objective : 1. To determine the linear relationship between absorbance and concentration of an absorbing species. 2. To study the effects of molecular dissociation complex formation on the applicability of the Beer-Lambert Law. 3. To investigate the derivation and limitation of Beer-Lambert Law. Introduction: In optics‚ the Beer–Lambert law‚ also known as Beer ’s law‚ the Lambert–Beer law‚ or the Beer–Lambert–Bouguer law relates the absorption

In comparison to many animals which do their gallivanting in the dark‚ humans cannot see in the dark because their eyes lack tapetum lucidum. This is a layer of tissues in the eyes which improves vision in low light conditions but is present in the eyes of most animals

This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges [23]. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum‚ molecules undergo electronic transitions [24]. Figure 4 shows the UV-Vis spectra of CAC and TAC. As seen from the data of Table 4‚ the electron transition from HOMO-2 orbital to LUMO orbital of trans isomer of azocubane (TAC) is happened

Effect of Ionizing Radiation on the Germination‚ Growth and Development of Corn (Zea mays L.) Alexis A. Parco BIO30 Group 1 Sec. A-6L September 27‚ 2012 ABSTRACT Corn seeds pre-exposed to 10‚ 30‚ and 50 kiloRads (kR) of radiation were grown in plots for almost 7 weeks. Four different setups – 10kR‚ 30kR‚ 50kR and the control‚ each with 10 corn seeds initially planted – were observed three times a week (during Mondays‚ Wednesdays and Fridays)‚ and the height of each growing corn was

EFFECT OF BREAKWATERS ON WAVE ENERGY DISSIPATION ABSTRACT The northern Egyptian coasts are subjected to many changes in shoreline balance due to waves and coastal currents. To protect and develop these coasts‚ many types of coastal protection structures have been used. This research demonstrates the effect of different systems of coastal protection structures on wave energy dissipation. By using the CGWAVE numerical model‚ the effect of each one and interaction between these structures on

The Visible Spectra Of Orange Soda Pop Objective : To measure an absorbance value of the different colour solutions by using Spectrophotometry Introduction Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color‚ or more specifically‚ the wavelength of light (nm). The instrument also can be use on biological sample such as chlorophyll pigments and
